BUMBLEBEE

The future of crop protection, redefined.

Why Bumblebee Is Different

Bumblebee is not just another spraying drone. It is a vision-led autonomous system built for tall crops, complex terrain, and real farm conditions where GPS, pilots, and conventional drones struggle.

VISION SYSTEM

Industry-leading visual intelligence
that sees every detail in the field

VISION SYSTEM

Market-leading visual intelligence

Bumblebee navigates by seeing the farm in real time. It stays dependable under tall canopies, uneven slopes, and cluttered plots.

Why vision-first autonomy works better

As farm environments become more complex, vision-led autonomy remains stable while GPS-first navigation loses reliability.

Vision-first autonomy GPS-first navigation
  • Continuous scene understanding
  • Decisions made onboard
  • Real-time depth cues
  • Designed for dense foliage
  • Smoother manoeuvres
  • Uninterrupted missions
  • Continuous micro-adjustments
  • Consistent coverage on slopes
AUTONOMY

Smarter obstacle bypassing

Built to keep missions stable in real farms where poles, trees, and uneven terrain are part of the plot.

TYPE 1 Lateral bypass around obstacles
TYPE 2 Overflight while spraying continuously

Type 1

In this mode, the system detects obstacles and avoids them laterally by planning a path around them.

Intended for crops where obstacles are present within the plot and must be bypassed while spraying.

SPRAY SYSTEM

Precision chemical delivery with adaptive control

SPRAY SYSTEM

Precision spray control, engineered for consistency.

Fine droplet control and stable spray patterns, tuned in real time to keep chemical dispensing consistent across the field.

Indicative comparison based on typical field behaviour. This visual is meant to explain why precision droplet control and stable spray patterns matter in real farms.

Spray output is dynamically calculated during flight based on operational parameters configured through the Ground Control Station.

  • Output adapts to spray volume, spray width, and flight speed
  • Continuous recalculation to maintain consistent dispensing
  • Improves spraying efficiency and overall productivity

A custom-engineered atomiser produces consistent and well-defined spray patterns during payload dispensing.

  • Stable droplet formation for uniform coverage
  • Predictable spray pattern across changing conditions
  • Adjustable atomiser angle to tune the spray pattern when required
PRECISION LANDING

Reliable landings with H-Marker guidance.

Designed for confined farm clearings. Bumblebee uses a visual landing marker to return to a predictable touchdown point, improving safety and turnaround between sorties.

Visual marker guidance helps achieve consistent landings in real farm conditions.

Works in small clearings

Built for plantations and tight plots where space is limited. The landing marker creates a clear reference point for controlled returns.

Safer turnaround between sorties

Predictable landings support quicker battery swaps and payload refills without improvisation, helping operators maintain smooth field flow.

Repeatable, operator-friendly setup

Place the marker, launch, and recover. The system is designed to make take-off and landing routines consistent across different farm environments.

FIELD OPERATIONS

Compact, single-operator deployment.

Designed for real farms where space is limited. Carry it in, power up, and launch from small clearings without a ground crew.

Single operator Carry and deploy
One person can carry Bumblebee to the plot and set up quickly.
Small clearings Plantation ready
Take-off designed for tight plantation spaces and uneven farm edges.
POWER AND UPTIME

Battery intelligence that keeps missions predictable

Real-time monitoring, fast swaps, and rapid charging are designed to minimise downtime and keep field operations moving reliably.

Quick swap Field ready
Battery insertion designed for fast turnaround between sorties.

PAYLOAD SYSTEM

Optimised payload design for faster turnaround

The payload system is engineered to support clean refills, consistent flow, and minimal interruption between sorties.

Quick refill Operational flow
Tank insertion designed for quick and controlled refilling in the field.

Designed for clean handling

Refill routines are simple and controlled, helping operators maintain a smooth spraying rhythm.

Consistent spray delivery

The payload system supports stable flow from start to finish of each sortie.

Built for repeat cycles

Tank insertion and removal are optimised for frequent use during full-day operations.

10 L payload capacity Faster refills Less idle time
OPERATIONS AT SCALE

Built to perform consistently across large operations

DGCA type certified

Bumblebee is designed for repeatable performance across multiple plots, long working days, and high-frequency sorties without operational fatigue.

6 min per acre spraying speed
< 2 min turnaround between sorties
All-day field operation capability

Plan once

Mission parameters are configured once and reused across multiple plots.

Execute repeatedly

Battery swaps and refills enable continuous sorties with minimal reset time.

Maintain consistency

Vision-guided autonomy keeps spray quality uniform across terrain and crop types.

FIELD-PROVEN RESULTS

Validated across crops, terrain, and operating conditions.

Bumblebee is deployed across real agricultural environments where performance is measured by consistency, efficiency, and outcomes in the field.

Rubber plantations

  • Improved canopy penetration in dense foliage
  • Higher leaf retention after spraying cycles
  • Consistent coverage on uneven terrain

Sugarcane fields

  • Reduced chemical usage through precise delivery
  • Uniform spray coverage under tall crop canopy
  • Faster completion of large plots

Banana plantations

  • Consistent spray quality across plant height variation
  • Lower manual intervention during operations
  • Improved operational efficiency per acre

Results reflect repeatable performance across multiple deployments, not controlled test conditions.
